Title Effectiveness of an ergonomic intervention on work-related posture and low back pain in video display terminal operators: A 3 year cross-over trial
Bibliographic information May 2010, Vol.41, No.4, p.436-443. Illus. 63 ref.
Abstract This study investigated the effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) in Video Display Terminal (VDT) workers. A total of 100 VDT workers were selected to receive the ergonomic intervention, while 100 were assigned to a control group. The two groups were then crossed-over after 30 months from baseline. Follow-ups were repeated at 5, 12, and 30 months from baseline and then at 6 months following crossover. Work-related posture and LBP point-prevalence were assessed using the Rapid Entire Body Assessment method and a Pain Drawing, respectively. The ergonomic intervention at the workstation improved work-related posture and was effective in reducing LBP point-prevalence both in the first study period and after crossover, and these effects persisted for at least 30 months. Findings confirm that individualized ergonomic interventions may be able to improve work-related posture and reduce LBP for VDT workers.
